Kind Code:
A2
Abstract:
The present invention relates to a road surface cutting apparatus comprising: circular fixing disks (10), the center of each of which has a main shaft coupling hole (12) for connecting a main shaft (11), and the outer circumferential surface of each of which is uniformly divided into sequential coupling portions (13), wherein each of the coupling portions (13) is inclined along the width thereof from one end toward the other end thereof; arc-shaped cutting blades (20), each of which has a length identical to that of each of the coupling portions of the fixing disk (10) and each of which protrudes outward further than the outer circumferential surface of each of the fixing disks (10), wherein the cutting blades (20) have sawteeth (21) sequentially formed along the outer surfaces of the cutting blades (20) such that a symmetrical tilt angle is formed between the sawteeth (21); and fastening members (30) penetrating through the coupling portions (13) of the fixing disks (10) and a plurality of connection holes (14, 22) formed through the surfaces of the cutting blades (20) to fasten the fixing disks (10) and the cutting blades (20) together. The present invention lengthens the useful life of each of the cutting blades (20) and enables partial replacement of damaged cutting blades (20), to thereby achieve improved convenience in terms of maintenance and to reduce costs.
